Terrestrial Very-Long-Baseline Atom Interferometry:Workshop Summary

This document presents a summary of the 2023 Terrestrial Very-Long-Baseline Atom Interferometry Workshop hosted by CERN. The workshop brought together experts from around the world to discuss the exciting developments in large-scale atom interferometer (AI) prototypes and their potential for detecting ultralight dark matter and gravitational waves. The primary objective of the workshop was to lay the groundwork for an international TVLBAI proto-collaboration. This collaboration aims to unite researchers from different institutions to strategize and secure funding for terrestrial large-scale AI projects. The ultimate goal is to create a roadmap detailing the design and technology choices for one or more km-scale detectors, which will be operational in the mid-2030s. The key sections of this report present the physics case and technical challenges, together with a comprehensive overview of the discussions at the workshop together with the main conclusions

Determinanten der Entscheidungen bei ALS-PatientInnen bezüglich lebensverlängernder und lebensverkürzender Maßnahmen

Background: Patients with amyotrophic lateral sclerosis are faced with different decisions in the course of the disease regarding life prolonging and life shortening treatments. Determinants of these decisions are rarely defined so far. The aim of this study was to identify possible determinants of the decision making process. Methods: A total of N=100 ALS-patients were interviewed with questionnaires concerning their decisions of life prolonging and life shortening treatments. Furthermore, possible determinants were acquired such as subjective feeling of autonomy, family bonding, subjective quality of life, depression, coping strategies, religiousness and cognition. Logistic and linear regressions were used for statistical analysis of the identification of determinants on decision making. Additionally, qualitative in-depth interviews (N=10) were performed and analysed by qualitative content analysis. Results: Family bonding was a strong determinant of decisions to prolong life. The majority (93 %) of the patients named the wishes of their caregivers as important for them and 79 % declared that the opinion of their caregivers influence their decisions. Similarly, increasing number of children of the patients showed a significant impact on the decisions to prolong life. Concurrently, the patients showed a strong need for autonomy which turned out to be a strong determinant of decisions to shorten life. Furthermore, degree of depression and religiousness had a significant influence on fatal decision making. Cognitive impairments however had no impact on decisions. Discussion: The results demonstrate a distinct discrepancy between the patients need for autonomy and the influence of the patient’s family bonding on their decisions. Patients that are more influenced by their need for autonomy decide towards life shortening treatments, whereas the patients that are influenced by their family ties tend to decide towards life prolonging treatments

Conservation status of the world's skinks (Scincidae): taxonomic and geographic patterns in extinction risk

Our knowledge of the conservation status of reptiles, the most diverse class of terrestrial vertebrates, has improved dramatically over the past decade, but still lags behind that of the other tetrapod groups. Here, we conduct the first comprehensive evaluation (~92% of the world's ~1714 described species) of the conservation status of skinks (Scincidae), a speciose reptile family with a worldwide distribution. Using International Union for Conservation of Nature (IUCN) criteria, we report that ~20% of species are threatened with extinction, and nine species are Extinct or Extinct in the Wild. The highest levels of threat are evident in Madagascar and the Neotropics, and in the subfamilies Mabuyinae, Eugongylinae and Scincinae. The vast majority of threatened skink species were listed based primarily on their small geographic ranges (Criterion B, 83%; Criterion D2, 13%). Although the population trend of 42% of species was stable, 14% have declining populations. The key threats to skinks are habitat loss due to agriculture, invasive species, and biological resource use (e.g., hunting, timber harvesting). The distributions of 61% of species do not overlap with protected areas. Despite our improved knowledge of the conservation status of the world's skinks, 8% of species remain to be assessed, and 14% are listed as Data Deficient. The conservation status of almost a quarter of the world's skink species thus remains unknown. We use our updated knowledge of the conservation status of the group to develop and outline the priorities for the conservation assessment and management of the world's skink species
